I had hyster (keeping ovaries) back in '99 age 32 , within months my ovaries were failing and developed meno symptoms, doc put me on 1mg oestrogen and it worked a treat, then within weeks everything came back so she upped it to 2mg
It may be that you need another increase ? But I've read here that it can a take a couple of months to settle in a regime, not what we want to hear when we're suffering
